No draw other than stalemate is automatic. Both draw by repetition and under the 50 move rule must be claimed (on the move they occur).
That's strange then. I have played at least two matches in the last few months drawing against an opponent right after I had offered a draw to my opponent, which got declined and the game ended in an draw due to repitition (as the main board indicated). I thought my opponents thought there was more in it for them so they decided to continue, but caused a draw by repitition after all. Strange...
